Suppose the current cost of gasoline is $3.10 per gallon. Find the current price index number, using the 1975 price of 56.7 cents as the reference value.
The current price index is _____
(Round to one decimal place as needed.)
The current price index is mathematically given as,$538.194
What is the current price index?By increasing the ratio of the current value to the reference value by 100, one can determine the index value.
Given that the current cost of gasoline is $3.10 per gallon. we need to find the current price index number, using the 1975 price of 56.7 cents as the reference value.
In regard to this issue, we have that:
Current value = $3.10
Reference value: $0.576
Typically, the mathematical formula for the Index price is,
I = (3.10/0.576) x 100
I= $538.194
The current price index number is 538.194

Answer:
Part a: x + 17 = 52 Part b: He should guess the number 35.
Step-by-step explanation:
In the equation, x stands for the number he has to guess. He is given the clue, "17 more than the number is 52." Therefore x + 17 = 52. Another equation you could use is 52 - 17 = x. This equation would be used to solve the problem. 52 - 17 = 35

a. DNE
b. 1
c. 3
d. 5
Answer:
c. 3
Step-by-step explanation:
You want to know the limit of the composite function f(f(x)) as x approaches zero.
LimitThe function f(x) can be evaluated at x=0. The graph shows the value to be ...
f(0) = 2
The function f(x) can also be evaluated at x=2. The graph shows the value to be ...
f(2) ≈ 3
The nearest value to f(f(0)) is 3.

The graph of a function is shown below. Use the graph of the function to find its average rate of change from x=-4 to x=2
Based on the interval, the average rate of change of the function is 4.0
How to estimate the average rate of change of the function f?The graph that completes the question is added as an attachment
From the graph, we can see that the equation of the graph is a quadratic equation
Also, from the question:
We have the interval to be:
The interval is given as
x = -4 to x = 2
This can be represented as
(a, b) = (-4, 2)
From the attached graph, we have
f(-4) = 22
f(2) = -2
The estimate of the average rate of change f is calculated as(to one decimal place)
Rate = [f(b) - f(a)]/[b - a]
Substitute the known values in the above equation
This gives
Rate = [f(2) - f(-4)]/[2 + 4]
Substitute the known values in the above equation
So, we have
Rate = [-2 - 22]/[2 + 4]
Evaluate
Rate = -4.0
Hence, the estimate (to one decimal place) of the average rate of change of the graph is 4.0

Marie is choosing a bag of apples to make into a pie. She thinks the pie will be tastier if it has more apples. The bag of green apples weighs 4.75, point, 75 pounds. The bag of red apples weighs 4.54, point, 5 pounds.
Which bag of apples should she buy?
red apples or green?
(from khan academy)
Marie should buy the bag with green apples as it has more weight hence it will have more apples eventually making her pie tastier
Comparison: When we compare, we look for similarities among the characteristics of other items or objects. Mathematicians use the concept of comparing and ranking numbers to identify the smaller and larger numbers and to determine whether they should be arranged in ascending or descending order.
Weight of bag with green apples = 4.75 pounds
Weight of bag with red apples = 4.54 pounds
Since the bag with green apples weighs heavier and contains more apples overall, Marie should purchase it because it will make her pie taste better.

This is an assignment may someone help me but not give me the answers just explain the steps I need to take
See explanation below
Explanation:
From the question, we are told line TV is perpendicular to line US.
This means the point which they intersect has an angle of 90°.
We are also told line TV bisects STU.
For a line to bisect an angle, it means it divided the angle into two equal parts.
When line TV bisects STU, it divided it into angle STR and angle UTR
Hence, ∠STR = ∠UTR
Also line SU and line and line VT intersect to give vertical angles.
Angle R and the angle opposite it are vertical angles.
Vertical angles are equal.
The angle with 90° and the angle opposite it is also a vertical angle.
you can see from the illustration. The two angles opposite each other are equal to 90°.
Since angle on a straight line = 180°
angle R + 90° = 180°
angle R = 180-90
angle R = 90°
All the 4 angles that result from the intersection line VT and line SU are equal to 90°

The measure of the angle is 1.0 when rounded to one decimal places.
What is right triangle ?If one of the triangle's angles is 90 degrees, the triangle is said to have right angles. The triangle with a right angle is known as a right triangle because a right angle is 90 degrees. Using the Pythagorean rule, it is simple to understand how the different sides of this triangle relate to one another. The greatest side of a right angle is known as the hypotenuse, and it is opposite the right angle. In addition, the right triangles are categorized as isosceles right triangles and scalene right triangles based on the other angle values. Pythagorean triples are another name for the right triangle's side lengths, which include 3, 4, and 5.
Given that : right triangle, we're provided the hypotenuse and the leg next to. We can use the cosine ratio to determine :
Cosθ =[tex]\frac{adjacent}{hypotenuse}[/tex]
Plug in the given information
Cosθ =[tex]\frac{4}{7}[/tex]
Use the inverse cosine ratio
θ = [tex]cos^{-1} \frac{4}{7}[/tex]
Plug this into your calculator (and ensure you're solving for radians instead of degrees in the settings)
θ =0.9626
Therefore, θ = 1.0 when rounded to one decimal places.
